ben. Posted July 15, 2003 Share Posted July 15, 2003 I listened more critically to my '56 University corner horn (AKA the largest patio speaker on town) last night, and noticed a rattle from the squawker. It was not distortion per se, but a vibration. The driver is a PAH (what a monster! about 3x the size of a k55 or ID30) mated to a Cobreflex horn. I removed the driver and it sounded like there was a pebble inside when I shook it. I took it inside and ran it off the HK430 with no horn. The rattle was still there. The diaphragm look OK from the front, but I'm not sure how to get it apart to conduct further examinations. There are 4 screws on the face of the compression chamber, but it still won't come apart with those out. Any diagnoses/suggestions? Thanks in advance Ben EDIT: Sorry, this probably should have been in Troubleshooting, but since we're all here anyway. (And there's no Mono Forum-what's up with that!? ) Quote Link to comment Share on other sites More sharing options...
